Ralston Instruments NPAK-KIT2-GR Nitropak Kit

Overview

The Ralston Instruments NPAK-KIT2-GR is an advanced portable nitrogen pressure calibration system with an internal compressed gas storage cylinder, precision pressure regulator, and volume controller. Designed for field technicians performing differential and static pressure calibrations up to 3000 psi (210 bar), it eliminates the need for external gas supplies while maintaining extremely fast and accurate pressure control.

Key Features

• Internal carbon fiber cylinder with 15.20 cu ft compressed gas capacity
• Precise piston volume controller with 0.0005 psi fine adjustment resolution
• LC20 pressure gauge rated to 3000 psi / 20 MPa with 1/4" Male NPT connection
• Pressure range from 400 inH2O (400 mbar) to 3000 psi using fine adjust piston and internal gas
• ABS plastic case with ergonomic handle and organized storage for hoses, adapters, and gauge
• No electronics — suitable for hazardous locations (North American Class 1 Div 1-2, ATEX/IECEX Zone 0-2)
• Multi-turn mechanical rotation (42 turns, pressure-balanced)
• Overpressure relief at 3300 psi / 230 bar
• Quick-test brass connections with caps and chains
